The paragraph is a macro language allowing execution of TCL statements, looping structures, data stacking, screen input and output, and branching.
A paragraph is an item stored in the current master dictionary whose attribute 1 contains the word paragraph. For compatibility with other vendors, PA and T are also accepted as paragraph indicators.
In its simplest incarnation, a paragraph is a list of TCL commands similar to a standard macro. However, paragraphs also allow other features which make it much more powerful.
